Steve power level has always fascinated most and others. From comic book statement like Preternatural, to the Perfect Human or even "Peak Human". But this is a little bit different. I'm curious of the times that he has just been called only "Super" human or even "Super" Man. These are the times that I have noted in my collections of the man known as Captain America. I'll start out with this one, and post others as well.
As Steve points out, that with Esrkine plan to create an army of Super Human Warriors. They would have also created Adamantium Robots to counter the Super Soldiers. But since they couldn't produce any army, as Steve was the only one of his kind. They most have feared these Super humans big time, as Steve is living proof of this.
